Try this: Enable the toolbar in View>Toolbars. Pull all of the toolbars off the top rows. Does the Extrude Tool toolbar show up in the upper left corner? If so, you have now found it and can place it where you need but you really ought to install the current version of SU2013. there was a bug in the first release that caused new toolbars to appear under the existing ones. It was fixed though.

Sometimes giving up helps!I reverted to the old plugins folder, relaunched SU and every toolbar appeared undocked, including ET!!! I relaunched it a couple of times and now it seems stable.finally to enjoy it (it's a great plugin).

Not a native speaker, point out my spelling (or other) mistakes, I won't be offended!!!

About the "edges by face" and "edges by faces" tools. Is it possible to specify which point on the face(s) the edge endpoint aligns with? E.g. can you start the extrusion from the one of the pointed tips of a star-shape instead of the centre of the centre of the face?

About the "edges by faces" tool. Is it possible to specify which endpoints on the starting face align/match-up with which endpoints on the ending face?

I hope these questions make sense. I've attached an image to show what I mean. Shape (A) was produced using the tool. Shape (B) I did manually by choosing which endpoints are matched and then using a curve-stitching tool.

The toolbar displays just fine in SU2013 unless you installed the plugin incorrectly or perhaps don't have sufficient privileges set for the Plugins folder. What operating system? (please update your profile), how did you install the plugin? Do you have sufficient privileges?

I'm afraid that I have to report a small bug.With the Extrude-by-rails (I didn't test the others). I have almost always an unexpected result if the profile turns exactly 180° around Z (didn' test for the other axes). It could be a 'division by (almost) zero' (tangent).

However, if you pick a 'sweeping rail' as the first profile, then the two 'end' curves as the rails, and the other 'sweeping rail' as the melding profile, then it works... The 'direction' of the form might twist unexpectedly.

Another solution is to rotate the 4 curves [temporarily] by say 1 degree, then it works as I think you had hoped - no 'twisting' etc...

See the screen-grab...

It's not so much trigonometry, more having to decide in which direction the mesh goes, obviously if it's a 50:50 chance with axial alignments it can guess wrong...

I have tested the SKP and get good results.See the attached image.The up/down orientation of the face does not affect the result.The over all size of the geometry is within sensible limits.

You errors...

EE Error 3:means that it is failing to add a curve from the cpoints it has got from the melding-profile...

EE Error 4:is a similar error relating to the profile...

I can't reproduce any errors... Your image shows one corrected located profile and one set on cpoints following a reversed curve, NOT the profile/melding-profiles lines... before the early failure Here are my thoughts...

Do you have Guides switched on?The toolset uses cpoints etc...

Your SKP is v6 - I don't have that version readily available to test so it might be a limitation - from available methods for your set up; although the API methods used are for >=v6 ?Why not upgrade to a newer 'free' version of SketchUp - it is much improved... v2013 'Make' ?Different versions can co-exists on the same PC.

Are you using the latest version of this Extrude toolset [v2.2] ?If not then please get the latest RBZ from the PluginStore pages... http://sketchucation.com/pluginstore?pln=ExtrudeToolsIf you have v8M2 or newer you can AutoInstall from the SketchUcation PluginStore dialog within SketchUp or use the Preferences > Extensions > Install... button to do it automatically for you...In SketchUp versions <8.M2 you'll need to rename the RBZ as a .ZIP file, and then extract its contents and manually move them into the Plugins folder***

[if you are not an Admin, make yourself an Admin using the Users Control-Panel: then make sure the Plugins folder has FULL read/write permissions set for every user/group listed under Properties > Security > Edit...]

***Always leave helper files within the same subfolder[s] that are inside the ZIP.

After an update restart SketchUp twice: as it'll need to remove older versions is you have a very out of date installation etc...

Lastly, what other plugins do you have loading?Are any of those quarantined or rogues, as explained in other posts ?

I have SKETCHUP PRO 2013 I installed the plugin ExtrudeTools V2.2 it works fine.

I installed SKETCHUP 2014 2 days ago to test this new version. Something does not work, can you, please take a look at the following pictures Perhaps the plugin is'nt up to date or there is something wrong with my machine !

If you get v2.2 of the tool's RBZ from the PluginStore and install it from the RBZ [i.e. don't drag+drop from an opened RBZ as if it were a ZIP file etc] you should then get fresh copies of all of the needed files [including the required helper "deBabelizer.rb"].The error you posted relates to an incompatible version of that file - old ANSI v new UTF8-without-BOM.The new version of Ruby used by SketchUp 2014 is less forgiving and cannot use that text file encoding.Most authors have updated their scripts to have the correct encoding, and thereby suit all versions of SketchUp.The files in this tool's latest PluginStore RBZ are all correctly encoded.To double check I have just reinstalled from a newly downloaded RBZ and it worked fine - the enclosed files are all correctly encoded - I checked

It looks like you copied an older one over from an earlier version's Plugins folder ?Reinstall properly, restart and retest...

Or have you installed anything else including deBabelizer.rb ?The few RBZs that do include it should all be correctly encoded if the latest versions are downloaded and installed...An old version will cause issues...
